Chapter One — Getting StartedYou are undoubtedly eager to unpack, set up, and begin using your new furnace. Getting started will be much easier if you carefully review the information in this chapter and follow the steps as outlined.

Before Unpacking • When you unpack your furnace, be sure to save the

carton and packing materials. These can be used again if there is a need to ship or return equipment.

• Be sure to read and save the printed shipping material packed with your furnace — it contains valuable information.

• DO NOT turn on the power to your furnace until you are instructed to do so.

Unpacking • If the packing materials and/or the furnace appear

to be damaged, call your dealer before continuing.

• Remove the furnace from the carton and place it on a flat surface.

• Look under the muffle, locate and remove the shipping hardware.

Lifting and CarryingNEVER ATTEMPT TO LIFT OR CARRY THE OVEN WITHIN ONE HOUR OF DISCONNECTING THE POWER AFTER IT HAS BEEN IN USE.

If you are preparing to ship the unit in its carton to a location outside your current facility, allow the furnace to cool with the platform down and, once it is cool to the touch, remove the white ceramic fiber firing tray from the table and pack it in the accessory box. Damage to the oven will result from shipment of the oven with the firing tray inside the muffle. Push the up button to run the table to the muffle. Install the shipping hardware underneath the table by reversing the above instructions.

Before the power is disconnected, use the front panel up arrow button to raise the platform to its full up position, then disconnect the power and wait at least one hour to allow the oven table and other surfaces to cool to room ambient temperature.

If you are relocating the oven inside the current facility or have used a protective glove to remove the firing tray from the table, continue below.

Remember to disconnect both the mains power cord and the pump accessory power cord and also remove the vacuum tubing from the vacuum inlet at the rear of the oven.

The oven weighs approximately 50 pounds (25 kg). A four-wheeled platform cart is recommended if the new location is more than a few feet away. Position the oven with the Mains Power Switch closest to the front edge of the work surface. Feel underneath the table and the table lift arm to ensure the surfaces are cool to the touch. Slide your right arm just underneath the table lift arm as close to the chassis as possible. Use your left hand to grasp the overhang of the chassis back just above the vacuum inlet. Raise the oven two inches, keeping it over the work surface until your back and arms confirm that you are able to control the oven without injuring yourself. Step back from the work surface and pivot slowly until you are headed in the desired direction. Reverse the above sequence to place the oven in the new location. Refer to page 5 to reconnect the power and vacuum ports.

THE OVEN SHOULD NEVER BE PLACED ON A FLAMMABLE WORK SURFACE. NEVER PLACE THE OVEN IN A LOCATION WITH OVERHEAD SHELVING OR CABINETS THAT COULD INTERFERE WITH THE VENTILATION SLOTS IN THE TOP OF THE MUFFLE HOOD.

Furnace Requirements• Turn on the furnace using the power switch located on

the left side of the furnace. The display will light up and the furnace will perform a series of internal self-tests. During these self-tests you will hear the pump turn on and off.

• The lift will lower. Place the firing tray on the center of the lift table.

• The furnace requires 120 VAC and 12 amps of current. A special heavy-duty power cord has been supplied with your furnace.

DO NOT OPERATE ON ANY OTHER POWER CORD. DO NOT OPERATE WITH AN EXTENSION CORD. OPERATING THIS FURNACE ON A CIRCUIT WITH OTHER FURNACES OR ELECTRICAL APPLIANCES THAT REQUIRE SIGNIFICANT POWER MAY CAUSE A CIRCUIT BREAKER TO TRIP. INSTALL THE HEAVY-DUTY SAFETY GROUNDED POWER CORD AND PLUG THE FURNACE INTO A GROUNDED OUTLET.

• Position the furnace so the front is facing you. Be sure to have at least eight inches on all sides of the furnace to allow sufficient air flow to keep the furnace cool. Do not place anything flammable near the furnace.

• Minimum ambient room temperature 60° F (15.5° C). Maximum ambient room temperature 80° F (26.6° C). Minimum relative humidity 45%. Maximum relative humidity 60%.

• The mains power On/Off switch is located on the left side of the chassis. It is a rocker-type switch with a “1” and a “0” symbol embossed on it. When the “1” side is depressed, the mains power will be applied to the oven. When the “0” side is depressed, the mains power will be removed from the oven. Never position the oven in such an orientation where the operator has to lean over the top of the oven to reach the mains power switch.

THE TRIANGULAR BLACK AND YELLOW STICKER ON THE FRONT CENTER EDGE OF THE MUFFLE HOOD IS A WARNING THAT THE METALLIC SURFACE CAN BECOME HOT TO THE TOUCH. NEVER PLACE YOUR HAND ON THIS SURFACE OR LEAN ON THE TOP OF THE HOOD WHEN THE UNIT IS IN OPERATION.

USE OF THIS OVEN IN ANY MANNER NOT PROSCRIBED IN THIS MANUAL MAY RENDER OPERATOR SAFETY FEATURES INEFFECTIVE.

Chapter Two — Special Function InputThe FireLite furnace has several special functions that allow the furnace operation to be customized to your needs.

Customize Program Finish TuneThe FireLite furnace has an unique feature to allow you to customize the tune that plays indicating a program is finished. This allows you to distinguish one furnace from another when a program is finished. FireLite allows you to program four tunes to play one after another. You need to enter the frequency and the duration for each tune. The furnace will play back all the tones right after they have been entered. You can reprogram the tones as many times as you want.

Setting Program Tunes:




4. Use the keypad to enter the frequency of the first tune. The four-digit display will show a default number and the two digit display will show FR. This indicates the frequency of the first tune. The larger the number the lower the pitch. The lower the number, the higher the pitch. The acceptable range is from 0 to 1,000 however, the recommended range of values are between 400 and 1,000.


6. The four-digit display will show a default number and the two-digit display will show DR. This indicates the duration of the first tune.

7. Use the keypad to enter the duration of the first tune. Generally 500 represents one-second duration. The higher the value, the longer the duration. The acceptable range is from 1 to 1,000 however, the recommended range of values are between 400 to 1,000.


9. The two-digit display will show FR to indicate the frequency of the second tune. Use the keypad to enter the frequency of the second tune.


11. The two-digit display will show DR to indicate the duration of the second tune. Use the keypad to enter the duration of the second tune.


13. The two-digit display will display FR to indicate the frequency of the third tune. Use the keypad to enter the frequency of the third tune.


15. The two-digit display will show DR to indicate the duration of the third tune. Use the keypad to enter the duration of the third tune.


17. The two-digit display will display FR to indicate the frequency of the fourth tune. Use the keypad to enter the frequency of the fourth tune.


19. The two-digit display will show DR to indicate the duration of the fourth tune. Use the keypad to enter the duration of the fourth tune.


21. The furnace will play the customized tune once. After that, the four-digit display will show the temperature of the furnace and the two-digit display will show the program number.

Note: Entering 0 as frequency would represent a silent or pause between note segments for the specified duration.

Note: The recommended range of duration of the tone is from 400 to 1,000 and the recommended range of frequency is from 400 to 1,000. The higher the number of duration, the longer the length of the tone. The higher the number of frequency, the lower the pitch of the tone.
